allmydata.test.test_client.Basic.test_ftp_auth_keyfile

Release-blocker because this is a new test for this release, and it should pass on all platforms.

[daira]

I can reproduce this. Looking at it now.

[daira]

For some reason the test is looking for _trial_temp\private\accounts, which does not exist, rather than _trial_temp\client.Basic.test_ftp_auth_keyfile\private\accounts which does. Will investigate further at Nuts & Bolts tomorrow.

[daira]

Oh, probably it's because a relative path private\accounts is being expanded relative to the working directory _trial_temp, rather than the node directory of the test. But why is that failing only on Windows?

[daira]

Fixed in [eb34e0d].

[daira]

The problem was that Windows used a different code path to expand the path, and that code path hadn't been updated to take account of the base parameter.
